The lime allergy test is a blood test that checks for an allergic response to lime. It is ordered when someone has had symptoms like hives, itching, or swelling after contact with or eating lime, and the cause is unclear.
What it measures
- Lime-specific IgE — Antibodies that target lime proteins; higher levels suggest sensitivity.
- Total IgE — A general measure of allergic tendency, not specific to lime.
- Cross-reactive allergens — Proteins shared with other citrus or pollens that may cause similar reactions.
Who it is for
This test is usually ordered by an allergist, immunologist, or primary care clinician when a lime allergy is suspected based on symptoms and exposure history.
Preparation
No fasting or special preparation is needed. Tell your clinician about all medications, especially antihistamines, as they may affect results.
Results and what they mean
Results are reported as a level or class for lime-specific IgE, often alongside total IgE. A clinician interprets these numbers with your symptoms and history; a positive test alone does not confirm an allergy. This is general information, not medical advice.

Frequently asked questions
Does a positive result mean I am definitely allergic to lime?
No. A positive result shows sensitivity, but only a clinician can diagnose an allergy after considering your symptoms and exposure.
Do I need to avoid lime before the test?
No, you do not need to avoid lime. The test measures antibodies that are already present in your blood.
Can this test tell me if I outgrew a lime allergy?
It can help track changes over time, but a clinician will decide if repeat testing is useful for you.
How long does it take to get results?
Results are typically available within 1 to 3 business days after the blood draw.
